Inthe business of sellingoil it is a common practice for the oil distributor to deliver his oil .in drums or cans which are the property otthe distributor and whichjare returned-to the distributor after the oil has been sold to be refilled and'used again. One ,diiliculty which the distributors have encountered has been due to the tact that dealers 'or'managers of "oil stations. it they are dishonest; will refill-a drum or can" with inferior and cheaper oil and sell it as the product of the original distributor.

The obiectoi the present invention is to furnishan oil can or eonti'iiner which is so constructed that it practically impossible in 1 the dealer or selierito refill the can in this way.

My invention consists in providing the oil drum .or container witha reed pipe through i which the drum is to be fllledor emptied and which is furnished with a checkvalveopening outwardly permitthe discharge of oil from the drum but fclosingjto preventthe drum from be-v ing refilled. ,Thevalve member or the check valve is .provided with a removable 9 which can be unscrewed from the valve member by inserti sa le! 1 a thmvsh t e feed ip constructed to enmewiththe movable cap'and" enable the, cap to be unscrewed trom the check valve. When the capis thus unscrewed it can 80 valve willbe left with open passage through which, the drum can be refilled with a'iresh supply of oil, The removable cap and key are" so constructed that the cap cannot:beunscrewed and removed exceptby some-one havinga special form of key'constructed to match and engage with the removable cap.

'Reterringto-the drawing, 1 vis an ordinary oil drum or container. 'lhis container is'provided 90 with a feed tube 2 which-is attached at its. upper end in any suitable way to'the top of the oil The'ieed tube extends downwardly in the drum, preterably to a point near the bottom thereot and is provided at its lower end with a check valve 3 which opens outwardLv so as to permit the oil to flow onto! the drum through the feed pipe and which closes when the oil flowsin'theother direction so as to, prevent the drum i'rom beins fin ed. .As is shownin the drawing thecheck valve is placed a considerable distance from the-outer end oi the teed pipe; 4 is a'pump or any construction by means at which the oil .canbe discharged from the drum. This pump is :shown diagrammatically" in Fig. i. The construction otthis pump is no part or the invention. It is adaptedto be screwed into the upper. part oi thejeed pipe;

I is thevalve proper which is hinged at 8 to theplate 5 sothat thevalve will swing-upwardlyand permit the elite flowout B of the drum. Thevalve proper is provided with a central aperture 9 which is-screw threaded as shown." lo is a removable cap provided with a 'projectionat; the lower end which is screw threadedas shown, thescrew thread of this projection being adapt d 50 888886 with the screw thread in the opening oil-the valve proper.

This key consists of a stem 14 having a handle 15 atthe topfand a socket onth'e check valvei- The socket piece 18 has a ;-reces's shape to vlit oi'the'removable cap.

' This socket-pleee-is provided with three projections-l'l. adapted toguide the'key'flwhen it is inserted in the feed tubes. One oi' these pro- 8 opening'upwa'rdly for that yonjiri the tubez -maining oil is allowe the projections-17, and by 25 which is adapted Jections 17 is provided with a central hole as shown in Fig. 3'in which a pin 18 is arranged to be moved back and iorth so that the inner end of the pin may engage with the groove 11 in the cap. The pin is pressed inwardly by a coil spring 20 placed in the hole in the projection 17 which spring can be adjusted by the nut 21 which is adapted to be screwed into the outer end 01 the hole or aperture inthe projection 1'7. The stem 14 of the key is made hollow so that it has a central passage as shown in Fig. 3 to receive the pin 22 which is adapted to be moved up and down in the key for purposes hereinafter explained. The upper end oi the pin 22 is .provided with a handle 23. The upper end of the teed tube 2 is provided with a vent 24 to permit the inflow, oi air when the oil is being removed from the drum. This is shown in Fig. 2 and is arranged so that itwill be left open when the pump 4 is inserted but will be closedwhenzthe drum has been filled and is closed by the cover to be screwed into the upper' endoi the feed tube 2 aiter'the drum has been filled and is ready for shipment.

The operation of my.'invention is as-iollows:

A drum fllledwith oil is sold to adealer or sup,- ply station. The] dealer or manager or the supply station'unscrews the cover '25 any suitable form of oil pump 4. When a select oil is made'the oil is pumped out ot the-drum in s'uchquantity as may be desired, the check valve purpose." When the some remaining the pump is unscrewed, the, re-
